Other mistake: Snow: After Grandpa turns the street into an ice rink, it cuts to Arnold in the backyard (by the garage) of Sunset Arms where he's been stowing logs in a storage container. When Grandpa shows up in the backyard and tells Arnold, "You got no play ethic," we see the fronts of Green Meats and Art's Shoe Repair behind Grandpa, but that's impossible because Sunset Arms is on the same side of the street as those two stores; we should only see the buildings/stores that are across the street from the boarding house.

The Aptitude Test / Oskar Gets a Job - S3-E9
Suzie: I gave you 100 dollars two days ago.
Oskar: Suzie, you know I had to use it to pay the phone bill.
Suzie: Oskar, they cut off our phone service this morning.
Oskar: I know, it's a terrible mistake. We should sue.
Suzie: Oh, Oskar, that just doesn't make any sense.
Oskar: Tell me about it. So, can I have the 50 dollars?
Suzie: I don't have 50 dollars, we've already spent my paycheck this week.
Oskar: What about your overtime?
Suzie: I work 20 hours a week overtime already, how many more hours do you want me to work?
Oskar: How about 25?
Suzie: OSKAR!

The List/Haunted Train - S1-E8
Question: Why did that boy steal Arnold's ball? Was that the whole reason he came to the park? He seemed awfully obnoxious and destined to ruin Arnold's day, just wanting more clarity. Thank you.
Answer: The episode doesn't really elaborate on who the kid was and what his motives were, so its pure speculation as to why he took it. Perhaps the kid could simply want a ball all for himself and decided to just take it, or was simply a rotten kid. The truth is the kid's motives are not important to the story other than it highlights Arnold was having a lot of trouble getting through the list.
